I sea known that 1, WILLIAM rgn eiimi, a citizen of theUnited States ofAmer-ic'a, re-Z .I 'sidin at Brooklyn, in the county of Kings ,-and-'tate ofNewzYork, have invented cer tain new and useful 1m rovementsinCon- .cr'ete Construction, of W 'eh-the following is J ther objectbeingto provide such a device" a: s ecificaticn, such asfz'will enablethosev skil edin the art to which it appertains to make; and. use thesame;

This. nventlon relates to concrete; con-j struction, and has for itsobject to provide a;

device to accurately age the distance'f-beeq .tweenthe sides of the'orm''as, for'instance,

in the'fformation' of awali of concretea fur-1 I whichwill" become acomponent part ofthe j wall when finished without the possibility of uneual shrinkage due to climat c conditlons or o defacing the said wallfrom rustor simi lar decomposition,- and a still further object" beingtoproVidesuch a de'vice which'issim ple in construction and veryinexpensive and whichpermits of' readily placing and disformations!lowing specificationfof which the 'accom placing the form necessary forsuch concrete My-invention is fully described in the fbl panyindrawings-form a part, in which suitthe several parts in each of theviews, and

the formation thereof.
